BED-SPRING SUFPORT.

Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed March 28. 1907- Seriallfo. 365.038.

To all whom it may concern:

Be it known that I, EDW'ARD RYAN, a citizen of the United States,residing at Clinton, in the county of Clinton and State of Iowa, haveinvented certain new and useful Improvements in Bed-Spring Supports; andI do declare the followin to be a full, clear, and exact description 0%the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in bed-spring supports, whichreinforce the bed-spring fabric to prevent the same from sagging, andwhich are capable of adjustment so that the said supports may be putunder any required tension and may be relieved of tension when the bedis in storage and not in use so as to avoid springing or warpin theframe, and which when in use may be adjusted to suit the unequal weightof two persons occupying the same bed, and my invention consists in theconstruction, combination and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is an inverted plan view of aspring bed bottom provided with adjustable supports embod 'ing myinvention; Fig. 2 is a longitudina sectional view of the same; Fig. 3 isa detail elevation of a modified form of the tension and adjustingdevices for the supporting reinforcing wire; and Figs. 4, 5, 6, 7 and 8are detail elevations of modified forms of the tension springs used inconnection with such wires.

The frame of the bed s ring is indicated at 1 and the bed bottom fabric, which may be of any suitable construction, is indicated at 2. Inaccordance with my invention, I provide a suitable number oflongitudinally-disposed supporting reinforcing wires 3, each of whichhas a hook 3 formed at one end, and has its opposite end screw-threaded.The same are here shown as having their major portions run through thebed sprin ined downwardly therefrom. To the opposite ends of the frame 1are attached hooks 4, each of which has a bill 5 at its outer endinserted in an opening in one end of the frame and'also has areversely-disposedbill tons of the said hooks rest on the upper sides 0the cross bars which form the ends of th e The intermediate por-' tachedto tension and adusting devices 8,

each of which is compose of a plurality of angle link-members 9. In theform of myinvention shown in Fig. 1, each tension and adjusting devicehas a pain of said angle link members pivotally connected together, asat 10, one of said members being pivotally connected to the bar 7, andthe other beingattached to the bill 6 of one 'of the hooks 4. Anadjusting screw 11 passes through openings in the said angle links andis provided at one end with an adjusting nut 12. Springs 13 coact withthe said link members and the said adjusting screws to normally draw thesaid link members toward each other to apply tension to the wires 3. Thesaid springs are here shown as coiled springs mounted on the ends of thesaid screws, one of said springs bearing between the head of one of thescrews and one of the link members 9,

the other spring bearing between the other link member and the adjustingnut.

The op osite end of each wire 3 passes through t e down-turned, bentportion 14 of a tension yoke 15,'Which is U-shaped and made of a singlepiece of wire. On thesaid end of the said wire 3 is screwed an adjustingnut 16. Washers 17 are placed on said wire, one of which bears againstsaid nut 16, the other bearing against the down-turned portion 14 of thetension yoke. A coile'd spring 18 on the said end of the wire 3 bearsbetween the said washers. Said tension yoke is attached to a tensionspring 19, which may be of any suitable form, various forms of saidapring being shown in Figs. 4, 5, 6, 7 and 8.

he said tension spring is formed with a plurality of s ring coils 20: ndis connected to the end 0 the frame opposite that to which the tensionand adjusting devices 8 are connected by being attached toone of thehooks 4. It will be understood that by turning the nuts 12, 16 to varythe tension of the springs '13, 18 and 19, the wires 3 may be put' underIn the modified form of tension adjusting device shown in Fig.3, saiddevice has two quired shape and also bent to form a plural-,

ity of spring coils 20. between which the stress is distributed, and theends of which merge inlink or arm portions 22, which connect said coilstogether and move angularly with refer,- ence' to one another undervariations of the stress exerted on the spring. Such provision of aplurality-of .coils and of angularly 'mov able vcoil-connecting portionsrenders such springs extremely strong and flexible. In

eachof the forms of the spring shown in Figs.

5, 6 and {,theends of thewire of which the sp g is made are directlyconnected together, as show'n at 23."

the wire ofwhioh it is com osed is bent to form two op ositely-exten ingarms 24.,- in the 'outer'en of each ofwhich is a relatively large coil20. The connecting portions be- .tween said arms include a relativelysmall plate 27, whic 'understo rei orc' supporting wires 3.

' While have herein described my invention as applicable .to a bedspring,vit will'be e that the same may beused in connection with s ringsfor other articles of furniture. 'It be observed by.reference to thedrawings that my improved tension and adjusting. devices are disposedunder the The end portions 25 of said spring emcee tion will be readilyunderstood without re.

quiring' a more extended explanation. Various changes in the form,proportlon,

and the minor details of construction may be resorted towithout-departing from the principleorsacrificing aigff the advantagesof] the invention, as d claims. v Havingthus described my invention,what I claim as new, and desire to secure by LettGIfPB,tGI I1J -IS, v

V 1. In combination with a bed or the like spring fabric anda frame,onwhich the sameed. bythe'appended is stretched, a supportingreinforcing wire v v for the spring fabric, attached to the 'frame, Inthe form of the spring shown in Fig. 4,

and,a'ten sion and adjusting device for said wireyconnected thereto andto the frame and 1 having .pivotally connected anglelinks, an. adjustingscrew connecting said links, and

springs coacting with said screw and links to exert tens on-on saidwire.

-2. In a structure of the cIass described, a

spring for the purpose set forth, made of a s ngle wire bent to formoppositely-extending arms, spring coils atthe outer ends of said arms, aconnecting portion betweensaid arms having a centrally disposed s ringcoil, and 5 terminal parallel portions, an a spring plate connecting theends-ofsaid parallel ortions.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. I

EDWARD RYAN.
